figure libraries (mkiv)

figure libraries (mkiv)

[Peter Rolf]

Hi Hans,

Looks like I'm the only one using resource libs. I have tried to solve
the problem with figure inclusion, but my lua is still too bad 
(coroutines). At least I have found the place where things go wrong.


function figures.bases.find(basename,askedlabel)
[..]
         if base[2] and base[3] then
             for e, d, k in 
xml.elements(base[3],"/(rlx:library|figurelibrary)/*:figure/*:label") do
                 page = page + 1
                 if xml.content(d[k]) == askedlabel then
                     t = {
                         base = file.replacesuffix(base[2],"pdf"),
                         format = "pdf",
                         name = xml.filters.text(e,"*:file"), -- always 
empty
                         page = page, -- wrong pagenumber (far too high)
                     }
-- tex.sprint(table.serialize(t))
                     figures.bases.found[askedlabel] = t
                     break
                 end
             end
         end
[..]


And what is the correct namespace for resource libraries?

You use rlx for the <library> element, and a joker for <subelements>.
The example in x-res-04.tex should be updated then (uses rl for all).
For testing I have changed the prefix to rl (as my test databases use rl).

I can send you a small 7z with my test files.


Peter

ok


if i use

"/(*:library|figurelibrary)/*:figure/*:label"

and exchange '*:file' in the upper code with 'rl:file' i get the correct 
name and page number. so in the end it's a filter problem (leave that to 
the experts) ;)

btw: currently only the 'name' is supported in mkiv. in mkii you can 
also use the real filename ('file') to access the graphic.

best wishes, peter
